@codespar/mcp-twilio

MCP server for Twilio — the global standard for programmable messaging and voice.

SMS, WhatsApp, and Voice across 180+ countries. Verify (2FA) and Lookup (phone validation) included. Fills the global messaging gap in a catalog otherwise tilted to Brazil-specific providers (Z-API, Take Blip, Zenvia, Evolution API).

Install

npm install @codespar/mcp-twilio

Environment

TWILIO_ACCOUNT_SID="AC..."             # required
TWILIO_AUTH_TOKEN="..."                # required (secret)
TWILIO_MESSAGING_SERVICE_SID="MG..."   # optional; default sender for send_message

Authentication

HTTP Basic auth with AccountSid:AuthToken. The server handles this automatically — you only configure the env vars.

Authorization: Basic <base64(AccountSid:AuthToken)>

API surface

  • Main Accounts API: https://api.twilio.com/2010-04-01/Accounts/{AccountSid} — Messages, Calls, IncomingPhoneNumbers
  • Verify API: https://verify.twilio.com/v2 — 2FA flows (requires a Verify Service SID passed per call)
  • Lookups API: https://lookups.twilio.com/v2 — phone number validation / carrier / line type

Request bodies are application/x-www-form-urlencoded; responses are JSON (endpoints use the .json suffix on the Accounts API).

WhatsApp

Use the same send_message tool, but prefix numbers with whatsapp::

{ "To": "whatsapp:+5511999999999", "From": "whatsapp:+14155238886", "Body": "Olá" }

Sandbox numbers or approved WhatsApp-enabled senders work the same way.

Run

# stdio (default — for Claude Desktop, Cursor, etc)
npx @codespar/mcp-twilio

# HTTP (for server-to-server testing)
MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-twilio
